serves to retain the heat incident to the cornbustion in the lower parts of the furnace, thus adding to the efficiency of the furnace. The air passages beingylrrunged in thcWa-lls of the furnace, the air takes up some of the heat fi'om the walls of the furnace so that air is delivered through the twyers 26 in a. highly hes-ted condition. ltwill bc'noted tlintt'ne air delivered in the upper passages is above the plate 9 and projects inwardly from said plate. This plate gives flexibility to the inward projection. The plate is provided with the openings 31 which register with the openings 22 and passages it is desirable to be able to remove th t-Wyers without disturbing much, if any, of the brick above them; for this reason I sup ply the key twycr shown in Fig. i. It is similsr in construction to the other twyers except that the top plate 9 and bottom plate 10 nnd partition 12 preferably have parallel edges so that the twver 8.5 9. Whole may be slipped in'ie place after the other twyers have con'mletc' the circle. The .ppiug plate 9 is arranged above the 0V9 l radial plated and this plate overlsps the adjacent plates ll. l. prefer lo make the penings between the uprights and partitions of :1 size which will permit of the in,- scrtioii of fire brick so that some of the pas-- sages may be closed in this way if desired. .ln' the alternative construction shown in Figs. 6., Y, 8, il s-rid 10 the ports of the twyer are separable. The top plate ll" bus the openings or slots 9", which are so arranged as to receive the tenous 'or lugs l1 on their upright-s ll. The bottom plate 10 has his slots 10', which are arranged. to receive the lemons "ll ll can readily be observed that by placing the uprights between the plates 9" and H)" with the tenons 11 and li in the sloisl) and 10 respectively, the twyer of numb the some construction as the preferred mnstruction may be formed. The twycr wvn in Fig. 10 is similar to the preferred Ox".'-"tr:.;ctlon except that'the horizontal portion 12 is omitted.

The twyer as shown in Fig. 11 is similar to that of the preferrml construction except that the plates 12 and 11-3" are substituted for the single plate. 12 sot-hut rhc twyer is separable along the horizontal plane between the pistes i2 :md 12''.

in 12 the uprights ll are separable, but each upright bus :1 top mid bot-tom plate 9 end if) respectively. The plates 9' end 10 are segmental shapes so that when s series of them are placed together the up rights 11 are properly s )aced. The plates 9 and 10 are preferably arranged above and below the uprights.

Whatl claim as new is:

l 1. In a furnace the combination of a series ow the bosh; said twyer comprising top I and bottom bites and uprights. between said plates, said uprights projecting at their tops inwardly toward the center of the furnscc and beneath the bosh.

4. In 8. furnace having itsfurnacermlls rovided with a. bush, 8. twyer arranged beow the bosh, said twyer comprising top and bottom plates and uprights between said plates. said upri hts projecting at their tops inwardly towarc the center of the furnace and beneath the bosb, said twyer beingformed in segments, each segment being no movable. 5. A furnace twyer having top and bottom plates and uprights arranged between said plates, said uprights projecting st their tops inwardly toward the center of the furnace, said twyer being provided with a horizontal partition between top andbottom plates.

6. A furnace twycr having top end bottom plates and uprights arranged between said plates, said uprights projecting at their tops inwardly toward the center of the furnace, and said twyer being provided with a. horizontal partition between to and bottom plutcs formed integrally with t e uprights. 7. A furnace twyer having top and bot-- tom plates and upri hts arranged between said plstes,said uprig ts'extending integrally from top to bottom of the twyer, and said twyer being provided with in horizontal partition between top and bottom plates formed integrally with theuprights.

in it furnace having its furnace wells provided with it bosh, a twyer arranged below the bush; seli'd twyer comprising top and bottom plates and uprights between. said plates, said upri hts projecting at their tops inwardly toward the center of the furnace and beneath the bosh, said twyer being cut away in its rear portion toform an air space communicating with the twyer.

l). 111 u. furmrec the combination of the twyer form of top and bottom plates and. uprights between said plates, said uprights projecting at their tops inwardly toward the center of the furnace and piate 30 arranged 5 above the top plate and extending inwardly beyond the edge of the uprights.

10. In a furnace the combination of a twyei' form of top and bottom plates, with uprights between the plates, the said up- 0 rights being formed integrally with said plates and an overhanging plate 30 arranged on the top plate and extending inwardlytoward the center oi the furnace beyond the edges of the uprights.

a 11.. A fiirnace twyer having top and bottom plates and uprights between said plates,

said uprights projecting at theintops intirardly towards the center of the furnace and said uprights being cut nway at the rear for the purpose described.

i2. A furnace twyer having top and bottom plates and uprights between said plates, said u rights being forn'ied integrally with said p ates and they outside uprights being 5 cut away at the rear for the purpose described.

o 13. A furnace twyer having top and hottorn plates and uprights between said plates, said uprights projecting at their tops in- 0 wardly toward the center of the furnace and being cut away at the rear for the purpose described, said uprights being formed integrally with said plates.

1 In a furnace the combination of a se- 5 ries of segmentally formed twyers having top and bottom plates and uprights between the plates, the uprights projecting at their tops inwardly toward the center of the furnace and the furnace shell, said uprights being wed in front of the said shell, forming an air soar-e between the shell and the uprights for the purpose described.

' if). in a furnace the combiuatimi of a series of segmentally formed twyers having top and bottom plates and uprights between the plates, the uprights projecting at their tops inwardly toward the center of the furnace and the furnace shell, said u rights being placed in front of the said she l forming an air space between theshell and the uprights for t 1e purpose described, said uprights being formed integrally with said plates.
